[Can intensive home care solve the problem of overcrowded psychiatric beds?].

The growing demand for psychiatric care raises questions about the place and value of alternatives to hospitalization. Community-based intensive care, such as home-based intensive care teams, are models that have been extensively studied and precisely described in international literature. They make it possible to avoid or shorten hospital stays, and have interesting variations for providing access to care in rural areas.

Achieving a Successful Scale-Down Model and Optimized Economics through Parvovirus Filter Validation using Purified TrueSpikeTM Viruses.

Unlabelled: This article describes a four virus panel validation of EMD Millipore's (Bedford, MA) small virus-retentive filter, Viresolve® Pro, using TrueSpike(TM) viruses for a Biogen Idec process intermediate. The study was performed at Charles River Labs in King of Prussia, PA. Greater than 900 L/m(2) filter throughput was achieved with the approximately 8 g/L monoclonal antibody feed.

[Advanced directives in psychiatry: A review of the qualitative literature, a state-of-the-art and viewpoints].

Background: Advance Directives are written documents, which are used for people to notify their preference for a future situation when they are unable to give their consent. In psychiatry, psychiatric advance directives (PADs) can be used for patients with chronic psychotic disorders such as schizophrenia, or a bipolar disorder. PADs give the patient an opportunity to state wishes in advance about his/her treatment when he/she is in an acute state of illness.

[Towards early diagnosis of schizophrenia].

Schizophrenia is a serious, chronic illness which, when treated early, can result in a better prognosis. The putting in place of treatment is often delayed because it is difficult to identify early schizophrenic disorders. At this stage of the illness, the doctor participates as much as the family and the patients themselves in the delay of the diagnosis.

Glucosylated hydroxymethyluracil, DNA base J, prevents transcriptional readthrough in Leishmania.

Some Ts in nuclear DNA of trypanosomes and Leishmania are hydroxylated and glucosylated to yield base J (β-D-glucosyl-hydroxymethyluracil). In Leishmania, about 99% of J is located in telomeric repeats. We show here that most of the remaining J is located at chromosome-internal RNA polymerase II termination sites.

Impact of virus preparation quality on parvovirus filter performance.

Virus-removal filtration technology is commonly used in the manufacturing process for biologics to remove potential viral contaminants. Virus-removal filters designed for retaining parvovirus, one of the smallest mammalian viruses, are considered an industry standard as they can effectively remove broad ranges of viruses. It has long been observed that the performance of virus filters can be influenced by virus preparations used in the laboratory scale studies (PDA, 2010).

RUNspike, a complementary virus filter spiking method: a solution to the problem of reduced throughput due to the addition of the virus spike.

The traditional approach to virus filter spiking studies (virus added to the feed solution before the start of filtration) can lead to oversized viral filtration systems because of the non-representative volumetric throughputs (L/m2) that can be seen with the addition of the virus spike. The reduction in throughput is thought to be caused by interactions that take place between the species in the virus stock solution alone, or in conjunction with the species in the drug product. The traditional approach assumes that virus filter log reduction value (LRV) is directly related to volumetric throughput and limits manufacturing scale designs to the volumetric throughput achieved in the spiking study.

Comparison of favorable early-stage hodgkin's lymphoma treatments: a single-institution review.

Purpose: To compare outcomes of patients receiving combined-modality chemotherapy and radiation (CMT) vs. other approaches for early-stage Hodgkin's lymphoma (HL).

Methods And Materials: A review of patients with nonbulky, early-stage (IA/IIA) HL treated between 1984 and 2002 was performed to determine the treatment approaches used and the outcomes obtained.

Evidence that J-binding protein 2 is a thymidine hydroxylase catalyzing the first step in the biosynthesis of DNA base J.

The genomic DNA of kinetoplastid parasites contains a unique modified base, beta-d-glucosyl-hydroxymethyluracil or base J. We recently reported that two proteins, called J-binding protein (JBP) 1 and 2, which regulate the levels of J in the genome, display features of the family of Fe(II)-2-oxoglutarate dependent dioxygenases and are likely to be the enzymes catalyzing the first step in J biosynthesis. In this study, we examine the effects of replacing the four conserved residues critical for the activity of this class of enzymes on the function of Leishmania tarentolae JBP2.

[Prevalence of trauma-related disorders in the French WHO study: Santé mentale en population générale (SMPG)].

Introduction: Trauma-related disorders are disabling affections of which epidemiological data change according to the country, population and measuring instruments. The prevalence of posttraumatic stress disorder (PTSD) appears to have increased over the past 15 years, but one cannot tell whether it has indeed increased or whether the standardized procedure has improved. Moreover, very few epidemiologic studies among the general population have been conducted in Europe, notably in France.

[Can concepts of neurodevelopment and neuroplasticity explain post-traumatic psychoses?].

Cases of psychoses emerging after a brain injury, included in the diagnostic category "Pychotic disorder due to traumatic brain injury," are not rare in psychiatry. The authors suggest hypotheses aimed at furthering the understanding of the pathogenic mechanisms relating traumatic brain injuries to psychotic disorders. These hypotheses find their starting point in two concepts: neuronal plasticity and the neurodevelopmental theory of schizophrenia.

Filter preconditioning enables representative scaled-down modelling of filter capacity and viral clearance by mitigating the impact of virus spike impurities.

Endogenous and adventitious virus removal by size-exclusion membrane filtration is a critical dedicated step in an overall viral clearance strategy employed by biologics manufacturers as required by industry regulators. However, the addition of impurities from virus spike preparations used in validation studies can significantly reduce filter capacity, resulting in an oversized and suboptimal virus filtration step. The hydraulic filter performance and virus retention observed in conventional scaled-downed validation models may not necessarily represent performance observed during process development, nor be predictive of manufacturing performance.

Contemporary management of stage I testicular seminoma: a survey of Canadian radiation oncologists.

Recently published studies clearly indicate that there are now several acceptable options for managing stage i testicular seminoma patients after orchiectomy. We therefore decided to survey Canadian radiation oncologists to determine how they currently manage such patients and to compare the results with previous surveys. Our results demonstrate that adjuvant single-agent chemotherapy is being considered as an option by an increasing proportion of radiation oncologists (although it is not considered the preferred option), the routine use of radiotherapy is declining, and surveillance is becoming increasingly popular and is recommended most often.

A protein of the leucine-rich repeats (LRRs) superfamily is implicated in antimony resistance in Leishmania infantum amastigotes.

Pentavalent antimonial containing drugs (SbV) are the mainstay for the control of the protozoan parasite Leishmania but resistance to this class of drug is now prevalent in several endemic areas. We describe here the use of functional cloning where an expression cosmid bank derived from Leishmania infantum was transfected in L. infantum axenic amastigotes and selected for potassium antimonyl tartrate (SbIII) resistance.

A 15-year analysis of early and late autologous hematopoietic stem cell transplant in relapsed, aggressive, transformed, and nontransformed follicular lymphoma.

Autologous stem cell transplant (ASCT) has been shown to be an effective treatment for follicular lymphoma (FL). We explored our experience in ASCT for FL among all patients treated over a 15-year period from diagnosis through their entire treatment history including relapse post ASCT. All patients who underwent an unpurged ASCT for relapsed, advanced FL between June 1990 and December 2000 were analyzed.

The protein that binds to DNA base J in trypanosomatids has features of a thymidine hydroxylase.

Trypanosomatids contain an unusual DNA base J (beta-d-glucosylhydroxymethyluracil), which replaces a fraction of thymine in telomeric and other DNA repeats. To determine the function of base J, we have searched for enzymes that catalyze J biosynthesis. We present evidence that a protein that binds to J in DNA, the J-binding protein 1 (JBP1), may also catalyze the first step in J biosynthesis, the conversion of thymine in DNA into hydroxymethyluracil.

Telomeric localization of the modified DNA base J in the genome of the protozoan parasite Leishmania.

Base J or beta-d-glucosylhydroxymethyluracil is a DNA modification replacing a fraction of thymine in the nuclear DNA of kinetoplastid parasites and of Euglena. J is located in the telomeric sequences of Trypanosoma brucei and in other simple repeat DNA sequences. In addition, J was found in the inactive variant surface glycoprotein (VSG) expression sites, but not in the active expression site of T.
